Narrowing searches based on url, author, date, and other attributes is also possible.
For instance, the query
[ Conan sourcename:Poynter ]
restricts searches for "Conan" to items from the blog "Poynter".
Examples of other operators follow:

• sourceurl:http://www.huffingtonpost.com/

items from the blog http://www.huffingtonpost.com/

• author:"Rupert Murdoch"

items by author "Rupert Murdoch"

• sourcename:"E-Media Tidbits"

items from blogs with "E-Media Tidbits" in the name

• title:substantiated

items with "substantiated" in the title

• date:01/28/10

items that appeared on 01/28/10

• body:"sharp gains"

items with "sharp gains" in the body

• date:[01/28/10 TO 02/04/10]

items appearing between 01/28/10 and 02/04/10

• link:http://www.apple.com/pr/library/2010/01/27ipad.html

items linking to http://www.apple.com/pr/library/2010/01/27ipad.html

Note: all operators that take urls will accept simple domain names, which match any item at that domain, or complete item urls.
